ONSI Corp., South Windsor, CT, reports that one of its first model PC25TM fuel cells has surpassed 40,000 hours of cumulative operation. The unit, owned by Southern California Gas, provides electricity and co-generated heat for the Hyatt Regency Hotel in Irvine, CA. "The durability of the cell stack is a true measure of commercial viability of fuel-cell power," reports Robert Suttmiller, president of International Fuel Cells, ONSI's parent company. Each of the 120 fuel cells in the ONSI fleet of PC25 power plants provides 200 kW--enough to supply electricity for nearly 150 homes. The cells use an electrochemical process to directly convert chemical energy into electricity and hot water. The chemical energy normally comes from hydrogen contained in natural gas. However, the cells do not burn the gas, so they operate virtually pollution-free. "The ONSI unit at Irvine has functioned with an operating availability of 95.6%," Suttmiller adds. "It has produced more than 7 million kW-hr of commercial-grade electricity, eliminating 200,000 lbs of pollutants that would have been created by power generators requiring combustion."

By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
